Abstract: A method and apparatus for the transmission of short data bursts in CDMA/HDR networks. Dormant access terminals are assigned to a common traffic channel and rate group by an access point. The access point then informs the access terminals of the assigned common traffic channels and rate groups. The access point then transmits short data bursts to the dormant access terminals using the assigned common traffic channels and rate groups. If an access terminal fails to acknowledge receipt of a short data burst, then the access terminal is re-assigned to a new common traffic channel and rate group and transmission of the short data bursts is re-attempted. If an access terminal fails to acknowledge receipt of a short data burst more than a predetermined number of times, then the access terminal is placed in an active mode of operation. The transmission of short data bursts may be further assigned to time slots within the common traffic channels and rate groups in order to conserve the resources of the access terminals.

Abstract: To perform wireless communications in a wireless network, at least two spatial beams are formed within a cell segment, where the at least two spatial beams are associated with different power levels. The at least two spatial beams are swept across the cell segment according to a sweep pattern. In some implementations, multiple antenna assemblies can be used, where each antenna assembly has plural antenna elements. A lower one of the antenna assemblies can be used to form high and lower power beams, and an upper one of the antenna assemblies can be used to communicate backhaul information, for example.

Abstract: An access network controller and a base station controller are formed to define an interface there between that enables the two systems to facilitate and respond to a voice call that is to be set up to a hybrid mobile station even though the hybrid mobile station is presently engaged in a data only call. More specifically, the base station is formed to generate a pseudo-page signal to the access network controller to determine whether the hybrid mobile station is present and available prior to the base station generating paging signals to establish the voice call. According to the response received from the access network controller, the base station either pages the hybrid mobile station to establish the voice call, forwards the call to voice mail, or forwards the call either to an Internet Call Delivery Server or to an Internet Call-Waiting Server.

Abstract: A method and system applicable within a mobile transmission system for adaptively allocating a downlink data rate to an access terminal to compensate for channel fading. In accordance with the method of the present invention a downlink data rate selected in accordance with a determined signal-to-noise level, wherein the downlink data rate is associated with a specified signal-to-noise threshold to achieve a specified packet error rate. Next, a packet is transmitted to an access terminal at the selected downlink data rate. In response to successfully decoding the packet at the access terminal, the signal-to-noise threshold specified for the selected downlink data rate is decreased such that subsequent data rate selections are adaptively maximized. Responsive to a packet decoding error, the signal-to-noise threshold is abruptly increased to maintain the specified packet error rate.

Abstract: A system determines an optimal set of base transceiver sets that are to transmit data over supplemental channels to a mobile station. A mobile station transmits periodic signal strength measurement message to rank the pilot signal strengths being received from the plurality of base station transceiver systems. Whenever the number of fundamental channel sectors that are active exceeds the maximum number of active supplemental channel sectors, periodic pilot strength measurement messages are transmitted by the mobile station. To improve resource usage, periodic pilot strength measurement messages are not transmitted as often as required to insure that the active supplemental channel sectors are the ones from which the strongest signals are received by the mobile station. Rather, a combination of periodic pilot strength measurement messages and calculated reverse link signal strength over spectral noise density values are used.

Abstract: To configure an IAB node for DU function and MT function resource transitions within an IAB network, the processing circuitry is to detect using allocated resources, a plurality of resource transitions in adjacent slots between transmission or reception of data on a parent backhaul link. The processing circuitry determines based on sub-carrier spacing (SCS) associated with the allocated resources, a guard symbol table with a number of desired guard symbols for each of the plurality of resource transitions. The number of desired guard symbols are for insertion during the transmission or reception of the data on the parent backhaul link to avoid overlapping of the allocated resources for the parent backhaul link and allocated resources for the DU function during the plurality of resource transitions.

Abstract: Embodiments of a Next Generation Node-B (gNB) and methods of communication are disclosed herein. The gNB may be configured with a gNB central unit (gNB-CU) and a gNB distributed unit (gNB-DU). The gNB-CU may determine a route for delivery of a data packet to a User Equipment (UE) on an integrated access backhaul (IAB) of relays. The gNB may generate a physical layer (PHY) data packet in accordance with a split between functionality of a packet data convergence protocol (PDCP) layer at the gNB-CU and functionality of a radio link control (RLC) layer at the gNB-DU. The PHY data packet may include the data packet, a PDCP header, an adaptation layer header, an RLC header, a medium access control (MAC) header, and a PHY header. The adaptation layer header may indicate one or more relays included in the route.
